Abstract: The present invention discloses a building roof structure formed by a skeleton, hollow assemblies, a waterproof layer and a heat insulation plate. The hollow assemblies are installed on the skeleton, the waterproof layer is paved on the hollow assemblies and the heat insulation plate is disposed above the waterproof layer. Hot air rising up inside the building and heat accumulated on the roof by being exposed to sun can all be circulated out through cooling spaces formed by the hollow assemblies, which achieves the cooling effect of natural air circulation to reduce temperature inside the building without using external fans or air drafting equipment. Therefore, the green building concept that saves energy and reduces CO2 emission is complied with, thereby improving the living quality of building.

Abstract: The objective of the unit 10 is mainly to adsorb Hydrogen Sulfide gas (also known as H2S) and other gases including but not limited to Carbon Dioxide 26 from plumbing, sewer, and wastewater management system vents 21 thereby removing the odor and or greenhouse gasses associated with the air stream/gas 26. The unique “T” housing 12 shaped design, along with the unique perforated disc containment system 14 holds the filtration media 16 in the horizontal portion 120 of the “T” housing 12. configuration allows fresh air circulation 28 to blend with the odorous gasses 26 passing through the filtration media 16 within the containment chamber and reduces their concentration (PPM) thereby increasing the life of the unit 10. Having the inlet to the filtration media at the base of the vertical portion of the “T” 120 and two outlets at the distal ends 119 of equal or greater size and diameter as each other or as the inlet, also reduces Pressure drop across the media 16.

Abstract: The present invention provides a ventilation system for an attic or rafter space that mimics the appearance of the roofing material and thus has little effect on the appearance of the building. The vent has two pieces, a primary vent and a secondary vent and they may be made of aluminum, galvanized steel or copper. The primary vent is installed on a roof deck over a ventilation opening cut through the deck. The secondary vent is constructed to look like the surrounding field tiles and is installed over the primary vent. One or more vent openings in the secondary vent and an opening in the primary vent conduct air between the attic or rafter space and the outside. The secondary vent has a skeleton with one or more vent openings and a cap covering each opening shielding the ventilating space. Skeletons are formed in one piece and are made to fit each different size and type of roofing tile. The caps and the skeleton are ribbed for rigidity.
